This is a constant struggle when it comes to card game designs, and I’m always trying to balance card power versus rarity. Daniel applies the Japanese concept of wabi-sabi, or basically not having perfect balance or distribution in something, that asymmetry has value. For fairness, I prefer balanced positions where players are equal and the outcome is based upon skill or luck, not drawing the ‘mega-sword of death’ card and being able to wipe other players off the board. I’ve tried to balance powerful cards with play restrictions, such as ‘remove from game after use’ so it’s a one-shot advantage.
Anyway, interesting reading.
